Rosa ‘RUIRI0126A’

ABSTRACT

A new and distinct hybrid  Rosa  cultivar named ‘RUIRI0126A’ is disclosed, characterized by pink-red flowers with a light floral fragrance, and glossy foliage. Plants are upright, and exhibit good resistance to blackspot diseases. The new variety is a  Rosa , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Rosa hybrida.

Variety denomination: ‘RUIRI0126A’.

BACKGROUND OF THE INVENTION

The new Rosa cultivar is a product of a planned breeding programconducted by the inventor. The cross resulting in this new variety wasmade May 2008 at a research nursery in Hazerswoude, the Netherlands.

The seed parent is the unpatented variety Rosa ‘NOA150097’. The pollenparent is the unpatented variety Rosa foliolosa ‘RUIBA028B’. The newvariety was selected in May 2011 by the inventor at the same researchnursery in Hazerswoude, the Netherlands. The inventor continuedobserving characteristics of the new variety for several years, in thecontrolled conditions of the research nursery.

Asexual reproduction of the new cultivar was performed by vegetativesoftwood cuttings. This was first performed at a greenhouse inAmstelveen, the Netherlands, in May 2013, and has shown that the uniquefeatures of this cultivar are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

The cultivar ‘RUIRI0126A’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘RUIRI0126A’ These characteristics incombination distinguish ‘RUIRI0126A’ as a new and distinct Rosacultivar:

-   -   1. Dark pink flowers.    -   2. Highly abundant flowering.    -   3. Glossy foliage.    -   4. Suitability for landscape and groundcover use.    -   5. Flowering continuously from June until October in the        Netherlands.

PARENTAL COMPARISON

Plants of the new cultivar ‘RUIRI0126A’ are similar to plants of theseed parent, in most horticultural characteristics, however, plants ofthe new cultivar ‘RUIRI0126A’ differ in the following:

-   -   1. The new variety has dark pink flowers, while the seed parent        has light red flowers.    -   2. The new variety has glossier leaf.

Plants of the new cultivar ‘RUIRI0126A’ are similar to plants of thepollen parent in most horticultural characteristics, however, plants ofthe new cultivar ‘RUIRI0126A’ differs in the following;

-   -   1. The new variety is a floribunda type, the pollen parent is a        multiflora type.    -   2. The new variety has pink-red flowers while the pollen parent        has white flowers.    -   3. The pollen parent develops a rose hip fruit not seen in the        new variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘RUIRI0126A’ can be compared to thecommercial variety Rosa ‘Noatraum’, U.S. Plant Pat. No. 7,282. Thesevarieties are similar in most horticultural characteristics, however‘RUIRI0126A’ differs in the following:

-   -   1. This new cultivar has larger flowers than this comparator.    -   2. This new cultivar has a more upright plant habit than this        comparator.

Plants of the new cultivar ‘RUIRI0126A’ can be compared to thecommercial variety Rosa ‘Korselary’, unpatented. These varieties aresimilar in most horticultural characteristics, however ‘RUIRI0126A’differs in the following:

-   -   1. This new cultivar has darker pink flowers than this        comparator.    -   2. This new cultivar has a more compact plant habit than this        comparator.
